<div class="moz-cite-prefix">So on these you are looking at how the
work done by the gas affects the volume. Basically you are using<br>

where the pressure is contant. The hardest part of this problem
is getting the units correct. The work is in joules, so the
pressure has to be in Joules. 1 atm = 101.325 J, and 1 atm = 760
torr. Work is also being done on the system, so <img

a negative sign.<br>

and you solve for <img style="vertical-align: middle"

<p>Hey Dr. Pounds,</p>
<p><br>
</p>
<p>I seem to be having a bit of an issue with number 7 in the
Chapter 5 Sapling. I cannot seem to figure out how to find the
final volume of the gas. I got it down to 1.49L/atm = 1.03atm
x Vf but I cannot figure out how to find Vf because when I
solve for it, I get 1.44L/atm^2 </p>
<p><br>

<p>Thanks.</p>
